About the Audi A3 Sportback 2024 boot
The Audi A3 Sportback boot is wide and square, better for bulk than for length. The opening is 38¼″ wide by 30⅜″ tall, and the narrow part of the floor still holds 39″ across, which is generous for this class. Seats up you get 30⅜″ of floor length, folding the rear bench takes that to 58⅝″, a gain of 28⅜″. The load lip is a low 26⅜″ with only a 6¼″ drop to the floor, so lifting boxes in is easy on your back. It swallows wide boxes, crates and a couple of cases side by side, but long flat-packs still need the seats folded. Load your widest item flat on the floor first, then build up.
About the BRIMNES Cabinet with doors, white, 30 3/4x37 3/8 " package
The BRIMNES cabinet arrives as one flat box, 39″ × 16¾″ × 6″, weighing 72 lb 7 oz. The size is friendly; the weight is not. At 39″ long it clears the folded load floor of almost any car, and plenty of boots take it with the seats still up, so this is one of the easier IKEA packages to move by car. What catches you is lifting 72 lb of dense flat-pack over a sill on your own. Slide it on its long edge rather than carrying it flat, bring a second pair of hands for the kerb and the stairs, and protect the corners; chipboard shows every knock at the edges.
